Overall, the population in this region resides in structures that are vulnerable to earthquake shaking, though some resistant structures exist. A magnitude 5.9 earthquake 146 km South of this one struck Argentina on November 19, 1973 (UTC), with estimated population exposures of 9,000 at intensity VII and 131,000 at intensity VI, with no reported fatalities. On November 19, 1973 (UTC), a magnitude 5.9 earthquake 146 km South of this one struck Argentina, with estimated population exposures of 9,000 at intensity VII and 131,000 at intensity VI, with no reported fatalities.

PAGER results are generally available on the Internet within 30 minutes of the earthquake’s occurrence. However, information on the extent of shaking will be uncertain in the minutes and hours following and earthquake and typically improves as additional sensor data and reported intensities are acquired and incorporated into models of the earthquake's source. Users of PAGER estimates should account for uncertainty and always seek the most current PAGER release for any earthquake.
